The essentials
the wheel condition and hub mounting surfa-
c e
s.
These surfaces must be clean before fit-
ting the wheel.
Wheel bolt tightening torque
The prescribed tightening torque for wheel
bolts for steel and alloy wheels is 120 Nm.
After changing a wheel, have the tightening
torque checked immediately with a torque
wrench that is working perfectly.
Before checking tightening torque, have any
rusty wheel bolts that are difficult to screw re-
placed and clean the wheel hub threads.
Never apply grease or oil to wheel bolts or to
the wheel hub threads. Even if the bolts have
been tightened to the prescribed torque, they
could come loose while driving. WARNING
If the wheel bolts are not properly tightened,
they c ou
ld come loose while driving and
cause an accident, serious injury and loss of
vehicle control.
● Use only wheel bolts which correspond to
the rim in question.
● Nev
er use different wheel bolts.
● Wheel bolts and threads should be clean,
free of oi
l and grease, and it should be possi-
ble to screw them easily.
● To loosen and tighten wheel bolts, only use
the wheel wrenc
h that came with the car from
the factory. ●
Loo sen the wheel
bolts only about one turn
before raising the vehicle with the jack.
● Never apply grease or oil to wheel bolts or
to the wheel hub thr
eads. Even if the bolts
have been tightened to the prescribed tor-
que, they could come loose while driving.
● Never loosen the screwed joints of wheel
rims with bo
lted ring trims.
● If wheel bolts are tightened below the pre-
scribed t
orque, the bolts and rims could come
loose while driving. If tightening torque is too
high, the wheel bolts or threads can be dam-
aged. CAUTION
When removing/fitting the wheel, the rim
ma y
hit and damage the brake disc. For this
reason, please take care and get a second
person to assist you. Tyres with compulsory direction of ro-
t
ation A directional tread pattern can be identified
b
y
the arr
ows on the sidewall that point in
the direction of rotation. Always observe the
direction of rotation indicated when fitting
the wheel to guarantee optimum properties
of this type of tyres with regard to grip,
noises, wear and aquaplaning.
If it is absolutely necessary to fit the spare
tyre* against the direction of rotation, drive with care as this means the tyre does not of-
fer optimum drivin
g properties. This is of par-
ticular importance when the road surface is
wet.
To return to directional tread tires, replace
the punctured tyre as soon as possible and
restore the obligatory direction of rotation of
all tyres.
Subsequent work ●
Alloy wheels: rep
l
ace the wheel bolt caps.
● Plate wheels: repl
ace the wheel hubcap.
● Return all tools to their proper storing loca-
tion.
● If the replaced wheel does not fit in the
spar
e wheel housing, store it safely in the
luggage compartment ›››
page 158.
● Check the tyre pressure of the newly moun-
ted tyr
e as soon as possible.
● In vehicles fitted with a tyre pressure indi-
cator
, adjust the pressure and store it in
memory ›››
page 287.
● Have the tightening torque of the wheel
bolts c
hecked as soon as possible with a tor-
que wrench (it should be 120 Nm). Mean-
while, drive carefully.
● Have the flat tyre replaced as quickly as
pos s
ible. 69
